United States Patent 3,395,639 METHOD OF WEBBING A NEWSPAPER PRINTINGPRESS George B. Swan, 505 Hicks St., Brooklyn, N.Y. 11201 Filed Nov. 16,1966, Ser. No. 594,723 1 Claim. (Cl. 101-426) ABSTRACT OF THE DISCLOSUREA method of webbing a multipress unit newspaper printing press whereineach press unit is webbed while the printing press is idle and theprinting plates are not on the type rollers.

The present invention relates to multipress unit newspaper printingpresses, and more particularly to an improved manipulative method ofarranging paper webs in the press units prior to putting such pressesinto operation.

Newspaper printing presses include a plurality of press units each ofwhich prints on both sides of a paper web to provide up to sixteen pagesof a newspaper, and a folder where the webs are collected to make up thenewspaper. Each press unit generally comprises a roll for supplying aweb of paper, first and second type rollers carrying printing plates,and first and second impression cylinders each co-operating with one ofthe type rollers to draw the web through the press unit and deliver itto the folder when the printing press is in operation. The press unitsare mechanically coupled to operate in synchronism and are each drivenby a 40 HP. electric motor.

Heretofore, in the operation of such printing presses the paper webswere arranged in the press units in the manner about to be described.Each unit was webbed individually and in succession by manuallywithdrawing paper from the supply roll and inserting the leading portionof the web between the first type roller and impression cylinder. Theprinting press was operated to advance the leading edge portion forinsertion between the second type roller and impression cylinder and todeliver the same to the folder. Each time another press unit was webbedin this manner the paper in the press units already webbed was furtheradvanced whereby the paper delivered to the folder was wasted until allthe press units were webbed and the printing press was in condition forproductive operation. In an eight press unit tabloid newspaper printingpress about 385 feet or 16.5 pounds of paper will be wasted by webbingthe press in the foregoing manner.

Accordingly, an object of the present invention is to provide a methodof webbing a multipress unit newspaper printing press for operationwithout wasting a large amount of paper.

A further object is to provide such a method which will effect a greatsaving in electric power by not starting and stopping the entireprinting press each time a press unit is webbed.

Other and further objects of the invention will be obvious upon anunderstanding of the illustrative embodiment about to be described, orwill be indicated in the appended claim, and various advantages notreferred to herein will occur to one skilled in the art upon employmentof the invention in practice.

In the drawings:

FIG. I is a schematic view of a newspaper printing press illustrating aplurality of press units, a folder and the manner in which the press iswebbed with paper.

FIG. II is an enlarged schematic view illustrating in 3,395,639 PatentedAug. 6, 1968 detail one of the press units shown in FIG. I and themanner in which it is webbed to the folder.

Referring now to FIG. I of the drawings in detail there is shown anewspaper printing press comprising eight press units A, B, C, D, E, F,G and H, by way of example, arranged in a row, and a folder 13 at themiddle of the row of press units. The press units and the folder are ona floor 14 and paper supply rolls 1 are on a floor 15 beneath the floor14.

As shown in FIG. II each press unit 12 has a roll 1 for supplying a webof paper 2, a first type roller 3 carrying printing plates, a firstimpression cylinder 16 co-operating with the type roller 3 to advancethe web of paper while one side of the paper is being printed, a secondtype roller 6 carrying printing plates, at second impression cylinder 17co-operating with the type roller 6 to advance the web of paper towardthe folder 13 while the other side of the paper is being printed, and anidler roll 4 over which the paper web passes as it is advanced from thefirst set (3-16) of type roller and impression cylinder to the secondset (617).

A number of rollers guide the paper web 2 as it is advanced towards thefolder 13, and co-operating rollers 7 and 8 deliver the paper webs 2 ofall the press units into the folder.

In accordance with the present invention, the printing press is put intoproductive operation by employing the method about to be described toweb each press unit. While the printing press is idle and the printingplates are not on the type rolls a web of paper 2 is drawn from thesupply roll by pressmen, the web is drawn upwardly and is passed betweenthe type roller 3 and the impression cylinder 16 by pressmen, the web ispassed over the roll 4, next the web is passed between the type roller 6and the impression cylinder 17 and is conveyed to the folder 13 bypressmen, and finally the leading edge of the web is placed between therollers 7 and 8 to hold the same in place and ready for delivery to thefolder.

The press units shown in FIG. I are webbed in the order of D, C, B, A,E, F, G and H.

When the leading edges of all of the webs have been collected and are'held in place between the rollers 7 and 8, the printing plates aremounted on the type rollers 3 and 6, and, when each press unit is inorder, the power source of the printing press is started to put the sameinto productive operation.

It will be observed that during the webbing of the press units the powersource of the printing press is not operated and that no paper isdelivered to the folder 13. This means that no power is consumed andvery little paper is wasted at the folder.

While the foregoing described method may be performed entirely manuallyby pressmen, the time required to webthe press units can be shortenedbyutilizing a mechanism for drawing and feeding the Web after it hasbeen passed over the roll 4. Such a mechanism comprises a drive rolleror trolley 5 co-operating with the roll 4 to advance the web, and a belt9 driven by a pulley 10 on the drive shaft of a small motor 11 to effectrotation of the roller 5.

When this mechanism is utilized, the web 2 is drawn from the supply roll1 and its leading edge is passed over the roll 4 as described before.The roller 5 is then placed into engagement with the web and the motor11 is started. This causes the leading edge to be advanced to the typeroller 6 and the impression cylinder 17 while more paper is drawn fromthe supply roll. The motor is operated until sufficient paper has beendrawn from the supply roll to enable the leading edge of the web to beconveyed to the folder. The motor then is stopped and the roller 5 ismoved out of engagement with the web.

It will be observed that this mechanism makes it much easier for thepressmen to handle the web than when all steps are performed manually.

From the foregoing description, it will be seen that the presentinvention provides a simple, practical and economical method of Webbinga multipress unit newspaper printing press.

As various changes may be made without departing from the spirit andscope of the invention and without sacrificing any of its advantages, itis to be understood that the matter herein is to be interpreted asillustrative and not in any limiting sense.

I claim:

1. The method of webbing a newspaper printing press solely in a presswhich includes a folder and a plurality of press units, each unit havinga roll for supplying a Web of paper and each until having first andsecond printing couples, each of said couples having a cooperating platecylinder and impression cylinder, and in the web path between each ofsaid first and second printing couples there being located twoperipherally cooperating drive rollers mounted for movement between anengaged and web-feeding position and a disengaged nonfeeding position,one of said cooperating rollers being driven by a [motor separate fromthe web-press drive and separate from the feed-roll drive of the otherunits, which method comprises performing the following steps in sequencefor each press unit while all of the units of the printing press areidle and while all of the printing plates are off of the platecylinders; drawing the web of paper from the supply roll; passing thewithdrawn we'b between the first plate cylinder and its cooperatingimpression roll; passing the web between the nip of said feeding rollerswhile said feeding rollers are in said disengaged position; engaging andactuating the drive rollers to thus grip and feed the web; guiding theWeb between the second plate cylinder and its cooperating impressioncylinder and to the folder While propelling the web with said drivenfeed rollers; disengaging and deactuating the said drive rollers;collecting and holding the leading edges of all the webs at the folder;mounting the printing plates on the plate cylinder; and thereafterstarting the printing press to put the same in productive operation.
